So, how do you get an accurate reading? Dr. Horberg said just wait.
“Your body quickly acclimates if its back in room temperature in about three to five minutes,” he explained. “You can then recheck your temperature and it should be back to normal.”
Dr. Meyer agrees. She said both the sun and infrared light can increase your skin temperature.
“If you’ve been outside In the heat for too long and you’ve worked up a sweat, exercising or running, your temperature on your skin will be hotter because you are trying to get rid of that heat,” Dr. Horberg explained.
